SAFE Toolbox

The modular structure of SAFE allows the user to easily plug in and out other matlab/octave functions and facilitates the integration of numerical models running under a different computing environment.

The SAFE Toolbox includes several visualization tools to investigate and effectively communicate GSA results.

All the methods implemented in SAFE comprise a set of functions to assess the convergence and robustness of the sensitivity indices.

Comprehensive documentation is embedded in the code throughout comments and a set of workflow scripts to get started.

The SAFE Toolbox provides a set of functions to perform Global Sensitivity Analysis in Matlab/Octave environment. It implements several methods, including the Elementary Effects Test, Regional Sensitivity Analysis, Variance-Based (Sobol') sensitivity analysis, and the novel PAWN method.
